How do I reliably expose MacPorts dovecot to the LAN on macOS Sonoma?

Sounds like a DHCP issue on your router that was cleared up after a reboot.

I’d recommend trying togging the network interface off/on the next time that happens, or rebooting the router.

I have used Murus (PF configurator/logger) to see that the connection from the outside is actually made. I tried Vallum (ALF configurator) to see what I could do/see.
